This antibody recognizes the ~78k Synapsin I doublet phosphorylated at Ser62,67. Immunolabeling of the Synapsin I band is blocked by preadsorption with the phospho-peptide used as antigen but not be the corresponding dephospho-peptide.

Synapsin I plays a key role in synaptic plasticity in brain (Feng et al., 2002, Nayak et al., 1996). This effect is due in large part to the ability of the synapsins to regulate the availability of synaptic vesicles for release. The role of synapsin in synaptic plasticity and in synaptogensis is regulated by phosphorylation (Jovanovic et al., 2001, Kao et al., 2002). Ser 549 along with Ser 62 and Ser 67 are the sites of Synapsin I that are phosphorylated by MAP kinase (Czernik et al., 1987, Jovanovic et al., 1996).Synonyms: Brain protein 4.1, SYN1, Synapsin I
